Not really...
Recent polls, like most polls of the last 6 months, suggest that the election will be very close. But I don't see where the seats will come from for the Tories to form another coalition (they have no chance of a majority and if they went with a minority government, who would vote through their issues?)
Clegg is polling badly in Hallam, so there's a good chance the Lib Dems will have a new leader after the next election. This throws things even more against the Tories.
A Labour minority government (with the SNP helping them vote through issues) seems most likely imo. But we shall see, it's all to play for whether red or blue.
This would be a disaster. The scots had a referendum on whether they wanted to stay within the UK, why can't England have the same? fudging tail wagging the brain-damaged dog is what that government would be.
